study the effect of structural changes through fungal biotransformation on the reported biologicalactivities of isoepoxypteryxin. Among the tested microorganisms, only Cordyceps sinensis had enzymes that could catalyze the ester hydrolysis and the reductive cleavage of the epoxide ring of isoepoxypteryxin, separately, to give two more polar metabolites (+)-cis-khellactone (P1) and a new coumarin derivative
